Are easterlies and trade winds the same?
The westerlies of the Southern hemisphere are more robust and constant than the westerlies of the Northern hemisphere. The Polar easterlies are cold, dry permanent winds that blow from north-east to south-west direction in the Northern Hemisphere and south-east to the north-west in the Southern Hemisphere.
These are extremely cold winds that come from the Tundra and Icecap regions of the poles. The Polar Easterlies are more regular in the southern hemisphere in comparison to the northern hemisphere. These polar cold winds converge with the warm easterlies near 60° latitudes and form the Polar front or Mid Latitude front.
When air moves in a definite direction, it is called wind. If the winds move from west to east, they are called westerlies. If they move from east to west, they are called easterlies. There are winds because there are differences in pressures.
Trade winds blow from east to west while the westerlies blow from west to east. Trade winds blow near the equator whereas the westerlies blow in the middle latitudes. Q: What is the difference between trade wind and westerlies?
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.
Prevailing Westerlies are the winds in the middle latitudes between 35 and 65 degrees latitude. They tend to blow from the high pressure area in the horse latitudes towards the poles. These prevailing winds blow from the west to the east steering extratropical cyclones in this general manner.
Westerlies are strongest in the winter, when pressure over the pole is low, and weakest in summer, when the polar high creates stronger polar easterlies. The horse latitudes are a narrow zone of warm, dry climates between westerlies and the trade winds.
Atmospheric circulation and the Coriolis effect create global wind patterns including the trade winds and westerlies. In the Northern Hemisphere, warm air around the equator rises and flows north toward the pole.
The trade winds were named by the crews of sailing ships that depended on the winds during westward ocean crossings.
3) The trade winds of the northern hemisphere are called the northeast trades and those of the southern hemisphere are called the southeast trades. (((((()))))))Westerlies = 1) Prevailing winds blowing from subtropical belts of high pressure towards sub polar belts of low pressure are known as the westerlies.
A region’s prevailing and dominant winds are the result of global patterns of movement in the Earth’s atmosphere. In general, winds are predominantly easterly at low latitudes globally. In the mid-latitudes, westerly winds are dominant, and their strength is largely determined by the polar cyclone.
The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth’s equatorial region.
